Description:

This diagnostic trouble code is generated when there is a data transfer problem between the PL1 control software and the PL4 control software. This issue occurs when messages sent on the CAN Bus by the PL4 control software are intermittently received or not received at all. Possible causes include an open circuit in the CAN Bus, a short circuit, or faulty CAN Bus terminators.

Reaction:

The control software may exhibit limited or no functionality due to communication issues.

Recommendations:

• Inspect CAN Bus Wiring and Connections:
  • Check for any open circuits, short circuits, or damaged wiring in the CAN Bus.
  • Ensure all connections are secure and free from corrosion.
• Test CAN Bus Terminators:
  • Verify that CAN Bus terminators are functioning correctly and replace them if necessary.
• Monitor CAN Bus Communication:
  • Use diagnostic tools to monitor communication between the PL1 and PL4 control software.
  • Identify and address any issues causing intermittent or lost messages.
• Consult Technical Support:
  • Seek assistance from technical support for further diagnosis and resolution if the problem persists.

Note:

Maintaining proper CAN Bus communication is essential for the reliable operation of control software. Regular inspections and prompt repairs can prevent such issues.
